Zusammenfassung:The current invention is directed to a system (30) for determining the refractive properties of an eye (10), the system (30) comprising a wavefront measurement device (32) for measuring the refractive properties of the eye (10), characterized in that the system (30) is configured to have at least one measurement mode assigned to children, wherein the system (30) has an input device (34) configured to switch the system (30) into one of the at least one measurement mode assigned to children, and wherein the system (30) is further configured to alter at least one of a group consisting of a default pupillary distance (54), a default cornea vertex distance (52), a default position (33) of the wavefront measurement device (32), a default position and/or direction of a measurement ray (58) of the wavefront measurement device (32), a default position (47) of a forehead and chin rest assembly (40) of the system (30) and a fixation target (38) when the system (30) is switched into the one of the at least one measurement mode assigned to children.
